Abstract: A nail retainer for a tacker comprises a guider receiving nails transmitted from a magazine, guiding the nails received therein, and comprising a hole formed through a designated portion of the upper surface thereof; and a stopper axially connected to the hole of the guider, moving together with the movement of a contact arm to prevent the nails received in the guider from dropping when the contact arm moves forward, and releasing a nail-stopping motion for preventing the nails from dropping when the contact arm moves backward. The nail retainer does not cause failure due to the attraction of iron filings remaining in a magazine or a guider onto the surface of the member, differing from conventional nail retainers made of a magnetic material, and moves together with the movement of a contact arm to reliably prevent a nail from dropping, thereby increasing the consumer's reliability.
